Example of getting the complete url address of the current page in php_PHP tutorial

In php, if we want to get the complete url address of the current page, we need to use several common php global variable functions, mainly using the variables $_SERVER[]. Let me show you how to get the complete url address of the current page. Program it.

Let’s take a look at some first

$_SERVER[ 'SERVER_NAME' ] #The name of the server host where the script is currently running.
$_SERVER[ 'QUERY_STRING' ] #Query string.
$_SERVER[ 'HTTP_HOST' ] #Contents of the Host: header of the current request.
$_SERVER[ 'HTTP_REFERER' ] #The URL address of the previous page linked to the current page.
$_SERVER[ 'SERVER_PORT' ] #Port used by the server
$_SERVER[ 'REQUEST_URI' ] #The URI required to access this page.

With some surface functions we can start

Let’s first look at some base methods

Two methods of baseUrl

Method 1:

The code is as follows

Copy code

代码如下	复制代码
// baseUrl function baseUrl($uri=''){  $baseUrl = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 'https://' : 'http://';  $baseUrl .= isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : getenv('HTTP_HOST');  $baseUrl .= isset($_SERVER['SCRIPT_NAME']) ? dirname($_SERVER['SCRIPT_NAME']) : dirname(getenv('SCRIPT_NAME'));  return $baseUrl.'/'.$uri; }

// baseUrl

function baseUrl($uri=''){
$baseUrl = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 'https://' : 'http://';

$baseUrl .= isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : getenv('HTTP_HOST');

代码如下

复制代码

/**      * Suppose, you are browsing in your localhost      * http://localhost/myproject/index.php?id=8      */     function baseUrl()     {         // output: /myproject/index.php         $currentPath = $_SERVER['PHP_SELF'];         // output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index )         $pathInfo = pathinfo($currentPath);         // output: localhost         $hostName = $_SERVER['HTTP_HOST'];         // output: http://         $protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https://' ? 'https://' : 'http://';         // return: http://localhost/myproject/         return $protocol.$hostName.$pathInfo['dirname']."/";     }

$baseUrl .= isset($_SERVER['SCRIPT_NAME']) ? dirname($_SERVER['SCRIPT_NAME']) : dirname(getenv('SCRIPT_NAME'));

return $baseUrl.'/'.$uri;

}

代码如下	复制代码
/** *@author mckee *@blog http://www.bKjia.c0m */ function get_page_url(){ $url = (isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443') ? 'https://' : 'http://'; $url .= $_SERVER['HTTP_HOST']; $url .= isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : urlencode($_SERVER['PHP_SELF']) . '?' . urlencode($_SERVER['QUERY_STRING']); return $url; } echo get_page_url(); ?>

Method 2:

The code is as follows

Copy code

/**      * Suppose, you are browsing in your localhost      * http://localhost/myproject/index.php?id=8     */ Function baseUrl() { // output: /myproject/index.php          $currentPath = $_SERVER['PHP_SELF']; // output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index )           $pathInfo = pathinfo($currentPath); // output: localhost          $hostName = $_SERVER['HTTP_HOST']; // output: http://            $protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https://' ? 'https://' : 'http://'; // return: http://localhost/myproject/            return $protocol.$hostName.$pathInfo['dirname']."/"; }

Method 3

The code is as follows

Copy code

/**<🎜>   *@author mckee<🎜>   *@blog  http://www.bKjia.c0m<🎜>  */<🎜> function get_page_url(){<🎜> $url = (isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443') ? 'https://' : 'http://';<🎜> $url .= $_SERVER['HTTP_HOST'];<🎜> $url .= isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : urlencode($_SERVER['PHP_SELF']) . '?' . urlencode($_SERVER['QUERY_STRING']);< 🎜> return $url;<🎜> }<🎜> echo get_page_url();<🎜> ?>

The following explains how to get the full path of the current page:

function getFullUrl(){
# Solve common problems
$requestUri = '';
If (isset($_SERVER['REQUEST_URI'])) { #$_SERVER["REQUEST_URI"] is only supported by apache,
         $requestUri = $_SERVER['REQUEST_URI'];
} else {
If (isset($_SERVER['argv'])) {
$requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0];
            } else if(isset($_SERVER['QUERY_STRING'])) {
$requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING'];
         }
}
// echo $requestUri.'
';
$scheme = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = strstr(strtolower($_SERVER["SERVER_PROTOCOL"]), "/",true) . $scheme;
$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
# Get the complete url
$_fullUrl = $protocol . "://" . $_SERVER['SERVER_NAME'] . $port . $requestUri;
Return $_fullUrl;
}

The code is as follows

代码如下

复制代码

function getFullUrl(){ # 解决通用问题 $requestUri = ''; if (isset($_SERVER['REQUEST_URI'])) { #$_SERVER["REQUEST_URI"] 只有 apache 才支持, $requestUri = $_SERVER['REQUEST_URI']; } else { if (isset($_SERVER['argv'])) { $requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0]; } else if(isset($_SERVER['QUERY_STRING'])) { $requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING']; } } // echo $requestUri.' ';     $scheme = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";     $protocol = strstr(strtolower($_SERVER["SERVER_PROTOCOL"]), "/",true) . $scheme;     $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);     # 获取的完整url     $_fullUrl = $protocol . "://" . $_SERVER['SERVER_NAME'] . $port . $requestUri;     return $_fullUrl; }

Copy code

echo getFullUrl(); Note: Since PHP does not have a built-in function, we need to combine the parameters on the url to achieve the entire url http://www.bkjia.com/PHPjc/631252.htmlwww.bkjia.comtrue
